Adding Intel DATALA memory events into perf mem record command: $ perf mem record -e list ldlat-loads : available ldlat-stores : available stlb-miss-loads stlb-miss-stores lock-loads split-loads split-stores all-loads all-stores l1-hit l2-hit l3-hit l1-miss l2-miss l3-miss lfb snp-miss snp-hit snp-hitm snp-none local-dram
All events from above lists are compiled in, but only those with [ok] are supported by kernel/HW. You need previous DATALA patch to support all of them.
